pressure head The potential energy possessed by a unit weight of water at any point when compared with a pressure of one atmosphere at the same elevation. For groundwater, it is measured by the depth of submergence between the measurement point and the water level in a piezometer. See also HYDRAULIC HEAD; ELEVATION POTENTIAL ENERGY; and POTENTIOMETRIC SURFACE.
